In the home market, there are many different brands of whole house reverse osmosis systems. Some of them cost thousands of dollars, but most do not. There is also a wide price range for these units, from low-end to high-end. The best whole house reverse osmosis system reviews are based on several factors.
RO systems that remove contaminants, rust, heavy metals, bacteria, heavy dirt and sediment are all sold in the high-end category. These are all sold in single or twin tanks, some of which can be used in combination to reduce the need for large and expensive filter tanks. The best whole house reverse osmosis system reviews for these products claim long lifecycles and excellent performance.
In the single tank configuration, some of the best membrane systems require a booster pump to operate at full capacity. This booster pump must be powerful enough to push out all the water produced by the osmotic membrane. It also must have the capability to maintain a constant flow rate into the unit’s primary filter so that all of the water produced by the unit is pumped through the filter. Some of the best membrane systems can have three or four individual booster pumps to accomplish this task.
Most of the systems are marketed as “smooth” or “tabletop” systems. The term “smooth” is used to characterize the method osmosis of the product. This involves a layer of semi-permeable film on the inside of the storage tank. As the liquid passes through the semi-permeable layer, it becomes trapped and can no longer flow through the membrane.
Tabletop reverse osmosis units employ the use of special glass fibers in the inside of the storage tank. The fibers are fine enough to trap particles on the inside, but are far finer than those found in the pores of real natural semi-permeable membrane. The filter life of these units will be significantly less than that of a home application. They also will not provide the level of pressure protection necessary for drinking water.
Home reverse osmosis systems are available in both table top and multiple stage units. These units usually have a high level of flow control. In other words, they can be set to produce clean water every day up to approximately five gallons. If the unit is connected to a home plumbing system, the pressure will be sufficient to help clean the water. However, the unit should be left turned off at the main water valve so that it does not contribute to rising water pressure levels.
For commercial applications, it is important to use multi-stage filtration systems. These are designed to remove sediment at a lower level than that required by a reverse osmosis systems. A multi-stage unit will typically contain two media layers. One media layer will remove large particulates and organics, while a second media layer is designed to trap small dissolved molecules such as those found in raw sewage. This will reduce the risk of cross-contamination of raw sewage coming into contact with drinking water.
The health risks associated with unfiltered drinking water are significant. These include gastrointestinal illnesses, urinary tract infections, allergic reactions to disinfection by chemicals, and the development of cancer. Reverse osmosis filtration cannot guarantee that these types of contaminants will not enter the body. Many are aware of the risks associated with drinking unfiltered water. Most simply choose to install an RO system. Others do not even consider the possibility of the possible adverse affects of this filtration method.
A multi-stage filtration system will include a variety of media to remove contaminants. Media can be a carbon filter, an ion exchange resin, or a variety of other additives. It is important to choose a filter with extended wear life. Extended wear life is what gives consumers confidence that their drinking water filter will work for years to come. The best units will have at least five years extended wear life.
Installing a reverse osmosis system for the home is an unnecessary investment that increases the consumer’s costs for bottled water. Instead, a consumer can invest in a multi-stage softener that removes the most contaminants, but leaves the minerals that are beneficial to health in the tap to ensure a clean and healthy glass of water. The most effective home ro system for removing contaminants, hardness and potassium is the reverse osmosis system.
There are other filters on the market that perform well. Most of them include a variety of features such as water softening capabilities and a variety of filters. Some of the top tier alkaline filters include two, three or four stages of filtration. For the home, the best system is the reverse osmosis system with the top tier alkaline filters.
